CABLE-CLAMP.

. Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed march 2, 1915. Serial No. 11,500.

To all whom it may concern:

Be it known that I, ISRAEL EVANS, a citizen of the United States,residing at Lenoir City, in the county of Loudon and State of Tennessee,have invented certain new and useful Improvements in Cable-Clamps, ofwhich the following is a specification.

This invention relates to cable clamps, and more particularly to thatclass of cable clamps in which a sliding dog is adapted to be forcedinto biting engagement with the cable by means of a suitable wedgemember.

The primary object of the invention resides in the provision of a clampof this character which is simple in construction and efiicient in itsoperation, the same engaging the cable firmly and securely withoutinjury thereto.

With the foregoing and other objects in view, the invention consists inthe novel features of construction, combination and arrangement ofparts, as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In the drawings: Figure l is a plan view of the improved clamp, showingthe same in engagement with a cable, Fig. 2 is a side elevation, Fig. 3is an end elevation, Fig. 4 is a sectional view taken on the line 4-4 ofFig. 3, Fig. 5 is a detail perspective view of the wedge member, andFig. 6 is a detail perspective view of the sliding dog.

Referring to the drawings by numeral, 1 designates a block which issubstantially lU-shaped in side elevation and which, comprises upper andlower arms 2 and 3, re-

spectively, and an intermediate portion 4,

the arms 2 and 3 extending in the same general direction from theinterinediat'e; portion 4 in parallel spaced relation;

A. dog: .5, which is substantially 'rectangu lar in shape, is adaptedfor sliding engagement between the arms 2 and 3 and has the inner facethereof formed in substantially semicircular shape and serrated, asindicated at 6, for biting engagement with the cable when the same isforced intoengagenient therewith by means of a wedge member 7. The cablebeing adapted to extend between the arms 2 and 3 and have one sidethereof engaged by the intermediate portion 4; and the opposite side bythe serrated portion 6.

The wedge member 7 comprises a head 8 and the split downwardly extendingportion 9, one face thereof being beveled, as indicated at 10. Thiswedge member 7 is adapted to be inserted in alining slots 11, formed inthe arms 2 and 3, and a slot 12 formed in the dog member 5, one face ofthe slot 12 being beveled, as shown at 13, to conform to the bevelededge 10 of the wedge member 7.

In applying the clamp to a cable, the same is first positioned betweenthe arms 2 and 3 of the block 1 and the dog 5 then inserted in theserrated face -6 thereof in engagement therewith. In this position theslots 11 and 12 will be alined, so that the wedge member 7 may bereadily passed thcrethrough. Upon forcing the wedge member downwardly,the dog 5 will be forced into biting engagement with the cable by reasonof the fact that the beveledface 10 is in engagement with the beveledface 13 of the slot 12. When the dog 5'has been forced into firmengagement with the cable, the lower ends of the split downwardlyextending portion 9 may be bent to engage the under face of the block 1,as clearly shownin dotted lines 'in Fig. 3 of the drawings, to lock thedog in its, clamped position.

From the foregoing description taken in connection with the accompanyingdrawings, it is thought that the construction and operation of thedevice will be clearly understood, and while I have herein shown anddescribed one specific form of my invention,

I do not wish to be limited thereto, except byvsuch limitations as theclaims may embrace. Havin 'thns'fully described lily-invention, what Ias new and desi e to secure by Letters Patent is:

1. A cable clamp comprising 'a substantially 'U-shaped block, a dogslidable between the arms of said block, the arms of said block providedwith co-axial openings,

said dog provided with an opening, and a wedge member arranged throughsaid openings, as and for the purpose set forth and described. i

2. A cable clamp comprising a substantially U-shaped block, the arms ofsaid block provided with coaxial openings, a do slid able between thearms of said block, sa1d dog provided with a substantially wedge-shapedIn testimony whereof I aflix my signature opening, a wedge memberarranged through in presence of two witnesses.

said openings to operate said dog the body of saidwedge member beingsplit whereby ISRAEL its lower ends may be bent to lock the same,Witnesses:

as and for the purpose set forth and de- T. J. CALLIER,
